H.265 HEVC vs VP9/AV1 : a snapshot on the video codec landscape

H.265 HEVC vs VP9/AV1 : a snapshot on the video codec landscape | pixels and pictures | Scoop.it

With the premium segment - led by Apple - now supporting H.265/HEVC, it is time content distributors leverage the massive user experience advantages of next generation compression (H.264/AVC was ratified back in 2003). Using ABR on congested networks an H.265/HEVC or VP9 stream can deliver HD whereas an H.264/AVC stream would be limited to SD. Of course this also saves bandwidth/CDN and storage costs.

 

The mass market segment lead by Google has decided not to support H.265/HEVC, but instead supports VP9. Despite lots of propaganda, VP9 can performs almost as well as H.265/HEVC (unlike most companies, we have built both encoders). So, post the 2003 H.264/AVC codec, both codecs will be required. Due to commercial and political reasons, both camps will not align around one next generation codec. In fact on a low cost Android phone priced under $100, it is impossble for the OEM to enable H.265/HEVC and have to pay royalties, since this would remove most of their profits. They will only enable VP9.

Philippe J DEWOST's insight:

Both shall prevail : this is the very insightful conclusion of a battlefield expert on the ongoing video codec war, with clear and interesting datapoints.

Nokia will acquire developers, technologies and intellectual property for imaging from Scalado. Nokia plans to make Scalado's headquarters in Lund a key site for Nokia's imaging software for smartphones, in addition to Nokia's existing locations in Espoo and Tampere, Finland.
The transaction is subject to customary closing conditions and is expected to close during the third quarter of 2012.

We put Instagram's Hyperlapse app to the test in Times Square

We put Instagram's Hyperlapse app to the test in Times Square | pixels and pictures | Scoop.it

Instagram has a new app out. It's called Hyperlapse and promises to help iPhone owners shoot smooth, professional-grade video clips. You can speed them up and make time-lapse footage, or chose a slower pace to see Instagram's special image stabilization algorithms in action. To keep things steady, Hyperlapse relies on your iPhone's gyroscope rather than searching for traditional scene references like angles and high contrast tracking points. Having to compute all that information would murder your battery, and turning to the hardware's existing sensors is a clever way of avoiding the hassle. Best of all, everything's done through an incredibly simple user interface. There are no accounts to set up or sign into. Not an Instagram user? It doesn't even matter.

Philippe J DEWOST's insight:

Wondering whether Instagram only got "inspired" by Microsoft Research's demos at Siggraph a few weeks ago, or if there are deeper "similarities" beyond Instagram releasing an iOS "flavor" of Hyperlapse... (see http://sco.lt/91e8vp)
